Why Are All Girls Born As Virgins?

What a confusing thread...Basically, girls are virgins because they have something called the hymen which protects the entrance to the vagina. That little mucous membrane exists perhaps for preventing infections and other kinds of stuff, or even to prevent sperm from getting in (which is useless when there is penetration).The cervical mucous works just the same way, only it is not a membrane, and is located at the entrance of the uterus itself.The question was why are all girls born as virgins. LOL, I must say. And now to the answer... First, we must admit that "virgin" is a social/cultural definition. Many women break their hymen long before their first sexual intercourse (for example, if they usually ride a bike). Other women are born with a small hymen, and other even have an imperforate hymen, which must be "broken" to allow for fertilization.The reason why this hymen exists is genetic... It is hardcoded somewhere in our genome. And why is it encoded in our genome? Well, because somewhere in the past, it must've been needed. Or even today :)I read somethings about cutting a cows ear and its descendents ears too to achieve a lining of earless cows. Well, that's just not gonna happen, lol. You see, those are changes that only affect the somatic part of the individual... For changes to be transmitted to the descendency, they must affect the germinal line's cells. Therefore, even though you just cut that ear right off, the cells which will in the future form the egg have all the information about having two ears, etc. And thus they are born with two ears, just like every girl is born with a hymen even though her mother already lost hers.Also, the thing about two twins having sex inside the womb... that's not very pretty to picture (i mean that's just sick) and besides, it's also impossible. Boys do not have erections inside the womb, for starters, and also, twins are usually in the 69 position separated by a physical membrane.Another thing! Even if they wanted, women couldn't start having babies after they were born... The follicles are not mature enough for that. Maturity is reached upon maturation of the endocrine system... which begins about the age of 10, 11 (depending from girl to girl)
